It's Always Sunny in Philadelphia: Season 11 (2015)
Seriously dark comedy about four dissolute friends who run a struggling pub in Philadelphia. Dennis, Dee, Mac and Charlie are absolutely (even gleefully) amoral. They're 'Seinfeld' characters on steroids, clowning their way through story lines that 'Seinfeld' writers wouldn't have touched.

Season 11, Episode 01 - “Chardee MacDennis 2: Electric Boogaloo”
In the 11th season premiere, the gang agree to a truce and demonstrate Chardee MacDennis for an interested board game executive, but things quickly go off the rails.
